fllhis ,invention relates to inmrovementsl in machines forlning can endswith` a sealing compound, and; especially to a machine adaptedvinterchangeably. to apply lining `*compound `to ianged can; ends of bothcircular i and` non-circular contour, like oval, square, rectangular orirregular shaped.

` One of theobsjectsof this `invention ils lthe provision of a machinefor applying lining compound fto aican end flange, whatever the contouror shape ofztheendtmay be.`

` "Another object of ithe invention isthe provision ofa machine of thischaracter, which `may be `readily converted from an arrangement`accurately lining a can end of one shape, into an arrangement forlining an end of "anientirely different shape.

Another ob]- ect of the invention istlie provision `of automatic meanspreventing the opening of'lthe compound nozzle, when a "cairendhas notbeen delivered to `receive the compoundwf y i .i .Y w

A further objectlof the invention is the `provision of a manualfcontrolVmechanism wherebyjthelopening Lofthe compound nozzle may Lbe prevented,whetherV there i was or was not a can-lend delivered.

1"With these obj ects in View the machine is `furnishedwith, a can endlmagazine, where the can 'endsare piledy by hand Orotherwise ina stack,and `,an `automatic Vfeeding `device is provided foruremoving thelowermost can end in the stack, delivering it upon a lower chuck,mountedupoii Athe end of `a swinging arm. .Theflowercliuck, `supportingthe can end, is then .elevated for a short distance, and brought into`engagement' with an upper chuck, "carried upon the end of another arm,clamping tliecan end between them.

\ and `then .they .are brought to -a stop and lowered to the originalelevation. y A nOzzlefada-pted to discharge sealing compound isstationarily secured above the chuck and furnishedwith a needle valve,adapted to beraised fromits seat and discharge seal-` ing compound intothe `curled ,flange of the pan endpsooni after the chuck started `torotate, and ithent-o be lowered upon its seat and stop the discharge ofthe compound, before the rotation of the chuck stops-` The needle valvekeeps `thenozzle open `for somewhat more than one `complete revolutionof the chuck. V

Means are provided to swing the chuck carrying arms towards and awayfrom `the nozzle," during the rotation of theirregular shaped can end,`so as `to keep `the centerline of the curled iange under the dischargeztip of the nozzle. y

After thechuck has been lowered, theautomatic feeding device removes thelined can end from the chuck, delivering it upon a dis- Figure 5 isa`vertical cross section of the'v machine drawn to a larger scale, andtaken 011 line 5-5 of Figure 2.

4form and size, corresponding with the form and size of the can ends,and of the guiding rods 4 secured to said base.

A recess 53 is cut on the lower face of the v base, as shown in figures2 and 8, and within said recess are fitted to slide the can end feedslide 54, and the can end releasing bars 55.

vThe purpose of the can end feed slide 54 is to move a can end, releasedfrom the stack 5, vand place it upon a chuck 22; and to remove a can endfrom the chuck, and place it upon a discharge conveyor 91; whilev thepurpose of the releasing bars 55 is to separate the lowermost can endfrom the rest of the stack, and drop it upon the surface of the table. iThe feed slide 54 is adapted to slide upon the'surface of the table 2,being guided by the guides 92; it is driven by a crank 58, secured uponthe vertical shaft 48, and connecting by means of a link 59 with a pin60, carried by the slide 54.

The can end feed slide is made with two prongs 65 and 66` and is formedwith the shoulders 93 and with the lugs 94, the former engage a can end,dropped upon the table by the releasing bars 55, and deposit it upon thechuck 22, while the latter engage a can end upon the chuck 22, anddeposit it upon the conveyor 91.

The releasing bars 55 are placed next above the feed slide 54; they aretwo in number, and

are situated one on each side of the slide. They are formed with theupturned lugs 56 and 57 and are adapted to slide longitudinally, beingguided in the recess 53.

The releasing bars are held normally by the springs 61 in the positionat the extreme forward end of their travel, resting with the set screws63, carried upon the lugs 57, in contact with the base plate 51, and aremoved in the opposite direction against the action of the compression Ysprings 61 yby the set screws 62, carried upon posts 64 near the ends ofthe prongs 65 and 66 of the feed slide 54, when said slide moves towardsthe can end stack, and return to the normal position at f the beginningof the forward stroke of the When the slide 54 is moving in a directionfrom the discharge conveyor towards the can end magazine, the releasingbars 55 remain at their normal position, and the can end stack isresting upon the lower supporting knife edges 98, the separating knifeedges 97 being forwards of the stack; upon the approach of the slide 54towards the stack 5, the releasing bars 55 move with the slide, theseparating knife edges 97 entering .the stack next above the lowermostcan end, leaving said can end rest upon thel `supporting knife edges 98,while the rest of the stack becomes supported by said separating knifeedges 97 at a short distance before the end of travel of the releasingbars in the direction 'from the discharge conveyor towards the stack,the supporting knife edges 98 move out from beneathV the lowermost canend, letting it drop upon the surface of the table, to become engaged bythe can end feed slide 54, upon its next forward stroke, and to becarried to the chuck 22.

Upon the forward stroke of the slide 54 the releasing bars follow theslide forwards, being driven by the springs 61. On the forward motion ofthe bars the supporting knife edges 98 enter beneath the stack, beforethe separating knife edges 97 move out from beneath it, letting thestack drop upon the supporting knife edges 98; in this manner the canends are separated and removed one by one from the bottom of the stackand placed upon the chuck 22.

The chuck 22 is adapted to rotate in a horizontal plane, is capable tomove for a short distance up and down, and has a swinging motion in ahorizontal plane together with a bifurcated swinging lever, upon the endof which it is mounted. f

At one side of the machine there are secured the bearings 10 and 11,Within which a vertical tubular shaft 12 is mounted, the upper end ofwhich extends for some distance above the upper bearing 10, where an arm30 is keyed. Below the bearing 10 the tubular shaft 12, carries abifurcated arm, co1n-A prising the long hub 16, and the upper and lowerprongs 17 and 18. I

The bifurcated. arm is also keyed to the tubular shaft 12, being inalignment with the arm 30.

Bearings 19 and 20 are provided on the prongs 18 and 17, within which aspindle 21 is mounted; said spindle extending above the bearing 20,where the lowerv chuck 22 is keyed, and extending below the lowerbearing 19, where a spur gear 23 for rotating the spindle 21 is secured;below the gear 23 a surface cam 24, having an outline corresponding tothe shape and v'size of the cam end, is fastened.

For imparting a swinging motion around the center of the tubular shaft12 to the bifurcated arm, a bracket 25 is secured to the frame of themachine, and avplate 26,

`plate73,"keeps the surface cam 24 in constant Contact, with said roller`28; the. rotation of `the cam 24 causing the swinging of the arm,

the?` tubular shaft 12 oscillating within the bearings a1-1d111.``

Thearm 30 is furnished with a bore 31, ari

l `ranged in vertical alignment With the spindle.

21-,`and within said bore a sliding sleeve34 is fitted; and* within saidsleeve a tubular stem 33, carrying the upper chuck disc 32 y is mounted;athrust ball bearing 35, and an annular ball bearing 36 being interposedbetween said stem and said sleeve.

The sleeve 34 is provided with a flange 37,

fitting inside thebore 31 at thebottom, while a glandf `38 screwed intothe upper part of the bore 31 guides the slgeeve at the top, and ahelical spring 39 surrounds the sleeve, engaging at the top the gland38, and pressing at the bottom against theflange 37, keeping the sleevenormally in aI downward position, the flange of a gland 69 which securesthe outer race of the annular ball bearing 36 to the sleeve,`serving asa stop.` n The upper chuck 32'is thus held down yieldingly by theVhelical spring 39, and rotates with little resistance.'`

The mechanism for raising and lowering the spindle 21 together with thelower chuck 221 consists of a forked lever 11() pivoted at 111 tothe hub16 of the bifurcated lever, and engaging at thefree forked end a block112,

` fitted upon the spindle 21, and heldin place bythe collars 113, anduofdevices for actuating said forked lever; thesaid devices are a cam 114,secured upon themain driving shaft 40 of the machine, engaging a roller115 carried upon the-end of one-arm of a bell crank lever 116, the otherarm engaging a roller 117, carried upon the lower endvof a rod 118connecting with said lever.

` The machine-is drivenfrom the main driving shaft 40, carrying the spurgear 42, which meshes `with an idler spur gear 43, revolving upon a pin44, and transmitting motion to a spur gear 45, keyed to the driven shaft41.`

The gear 42 Vof the driving shaft and the gear45 ofthe driven shaft areof the same diameter and pitch of teeth, and cause the a similar gear89, carried upon the vertical drive shaft 50, transmits continuous`motion to said shaft.

" `The driving shaft 40, the driven shaft 41, the vertical can endfeed-shaft 48, and the vertical drive shaft all revolve continu- V ouslyand at the same rate of speed, making one complete revolution, each`time a can end has been lined `with lining compound,

and the can end feedslide 54, driven by the vertical shaft 48,reciprocates also continuously, making a stroke forwards and back again,each time a can end is lined, the otherV devices in the machinev are sotimed, as to conform to the motion of said slide.

For imparting an intermittent rotation to the spindle 21 of the lower`chuck 22 the following mechanism is used. t

The vertical can endl feed shaft 48 is mounted at the lowerend in abearing 70, provided upon the cross plate 71 of the frame, and attheupperlend in a bearing 72, carried upon a cross plate 73 of theframe. i

A spider 74, provided with a long hub, is fitted to revolve freelyaround the shaft 48 and is: driven intermittingly from the shortvertical shaft 50, by the devices herein described; the spider connectsby a chain of gears with the spindle 21 of the chuck 22, causing itsrotation, and it is desired that said rotation be uniform during thetime lining compo-und is discharging into the curled iiange of the can`end, in order to distribute the compound more evenly; and it is alsodesired, that the starting and stopping of the rotation of the chuck begradual in order to insure the smooth working of the machine.

The device here used fulfills the above stated requirements, it is ofthe nature of a Geneva cam, as it also transforms a continuousrotarymotion ofone memberinto an.

intermittent motion of another, but differs in the nature of the motionproduced. The rateof acceleration at thestarting'and of de-` celerationat stopping in this device is such as to take up a small part of themotion, leaving the middle portion of uniform speed,

while in the resultant motion of a Geneva cam, there is no middleportion of uniform speed, it is all accelerating, or decelerating.

y The spider 74 inl this case is formed with six arms, and its rotationfor onesiXth part of a revolution at a` time is transmitted to thespindle 21 by means of the gear 75, securedf upon the hub of the spider74, engaging a` pinion 76on a` vertical idler shaft 7 7 ,mounted 1n thebearings78 and 79 at the side of the frame ofthe machine, while a largergear 8O,` secured upon theidlershaft 77, meshes with the gear 13,loosely mounted upon the tubular shaft 121,` imparting motion to it andto the gear 15, keyed upon the hub 14 of said gear 13; f

The gear 15 meshes with` an intermediate gear 81, which in turn engagesthe gear 23,;

keyedto thespindle 21, and causes its rotation. t

' The ratio of gearing between the spider gear and thegear'23 `ofthespindle is i 13o such, asto `cause said spindle to vrevolve for oneand one half of a revolution, each time the spider revolves for onesixth of a turn.

For transmitting intermittent motion to the spider 74 from the verticalshaft 50, there 5 are provided a plurality of antifriction rollers 82,mounted upon pins on the lower face of the spider, one on each arm,placed at equal distances from the center, and equally spaced one fromthe other; below. the spider is placed a disc 83, furnished with a hub84, whereby it is keyed to the shaft 50, and upon said disc is secured aflat cam 85, having an outline of such a shape, as to enter between twoadjacent rollers, and be 1n contact with both of them during therotation of the spider, the constant contact prevents any back lash inthe spider, giving it a smooth motion.

The ratio of the time the spider is in motion to the time it is at restdepends upon the distance between the shaft 48 and the shaft 50, and therate of acceleration at starting, and deceleration at stopping, dependsupon the curvature at the portion of the cam at both ends of its centerline; the sharper the curves, the more rapid the acceleration.

Since said curvatures may be varied in different cams, the desired rateof acceleration of the spider may be obtained, by giving the propercurve to the cam.

In the machine illustrated, the spider 74 is moved for a distance of onesixth of a revolution, during the rotation of the driving shaft 50through an angle of 110 and during the remaining 250, the spider is atrest in order to give time for the lowering of the lower chuck 22, forremoving a can end from said chuck, for withdrawing a can end from thebottom of the stack and place it upon the chuck, and for lifting thelower chuck 22 and bring it in contact with the upper chuck disc 32, inorder tov clamp the can end. j

In determining the distance required between the said shafts 48 and 50,it may happen, as in this case, that the center of the shaft 50 comesclose to the path of travel of the roller 82. When the roller is in theposition shown at 90 in Figure 4, the point of l contact of the camsurface with the roller being near the center of the shaft 50, saidpoint of contact has little motion, and in order to move the roller withthe required speed, it has to press upon the arm of the -spider in adirection too close to a radial line, thus subjecting the roller pin toan excessive strain; to avoid this strain, a roller 86 is mounted upon apin 87, carried upon the cam 85, and cam surfaces 88 are formed l uponthe arms of the spider. The roller 86,

the shaft 50, when the cam surface 85 acts upon them in a more favorabledirection.

The cam illustrated gives an accelerating motion to the spider during 9rotation of the same, then moves it for a distance of 42 at a uniformspeed, and at last brings it to rest within 9 of motion.

It is evident, that this can not be accomplished by a Geneva movement.

rlhe rotation of the spider for a distance of 60 around the verticalshaft is transmitted to the spindle 21, causing it to make one and onehalf revolutions, the middle portion amounting to more than one completerevolution being of uniform motion, and the rest variable. l

Above the table, adjacent the can end magazine, is secured a nozzle 6,containing lining compound under pressure; the nozzle is held within thebore of a bracket 7, mounted upon the table.

The nozzle is furnished with a needle valve, provided with a stem 8,whereby it may be raised olf its seat in the tip 9 of the nozzle,causing a stream of compound to issue from the nozzle, and dischargeinto the curled flange of a can end, held in the rotating chuck belowit, or it may be lowered, stopping the iiow of compound, after the chuckhas turned for more than one revolution, and filled the curled flange ofthe can end all around.

Can ends are generally provid-ed with annular grooves and ridges forstiifening them, and the'lower chuck 22 is formed with an oval groove 67and a ridge 68 accordingly.

lhen the spider 7 4 comes to rest, the chuck 22 also comes to rest,withthe major axes of the groove 67 and of the ridge 68 running in thesame direction as the axes of the can ends in the stack, as shown inFigure 7.

The can end slide 54, which transfers the can ends from the magazine tothe chuck 22, has the shoulders 93 so formed, as to maintain the` canend axes in the s ame direction, as they were in the can end magazine,insuring the registration of the grooves and ridges of the can ends withthose of the chuck, when the former are placed upon the latter.

4.After the slide 54 has moved a short distance on its return stroketowards the magazine, the chuck is raised, and then rotated for one andone half revolutions, while the slide moves to the end of the returnstroke, the lugs 94 passing beneath the chuck.

While the chuck 22 together with the spindle 2l and the cam 24 rotate,the latter, being held by the spring 29 against the stationary roller28, causes the swinging of the bifurcated arm towards or away from thetip of the nozzle, to an extent required to preserve the alignment ofthe nozzle with the groove in the can end iiange.

After the chuck 22 has completed one and o ne half revolutions, themajor axes of the chuck will again be in the same direction as properposition to receive another can end,

afterythe finished one has been removed by the lugs 94 of the slide 54.

The needle valve, controlling` the discharge of liningA compound intothefl-ange of the can end`,`,is operated by a. cam 99, carried upon themaindrivingshait 40, and safety devices are `interposed between said camand the stem 8 of" the needle valve, to insure the opening'of thenozzle, when a can end to be lined is present upon the chuck 22, and tokeep the nozzle closed, itthere is no can end upon the chuck to receivethe compound.

For raisingfand lowering the needle valve there is rovided a beam lever100, fulcrumed i at the middle upon a post 101, extending upupon the`main driving shaft 40, enaging a wards from an arm 102 of the bracket7, said beam lever engaging at one end a collar 103, secured to the"stem 8V of the needle valve, andi` carrying atthe other end a rod 104,

furnished at the lower end with a sleeve 105 provided at itslower endwith a tooth 1106, projecting-to oneside of it, and at its upper endwith a handle 107, whereby it may be given a turn. A bearing 108,secured to the trame 1, serves to guide the end of the rod 104. The rod(is held in an upward position by a spring 109, placed upon the stem 8of the needle valve, engaging at the lower end the collar 103, andresting at the top against theV guiding bracket 119, carried upon thebracket.

The rod 1104 is actuated by a cam 99, carried rol1er`120, mounted upon apin carried upon one arm` of a bell crank lever 121, pivoted at 122, toa bracket 123, while a tension spring 1275, acting upon the other arm,tends to keep the roller in contact with the cam, oscillating the bell,crank lever.

A hook bar` 124 is pivotedto the bell crank lever, said hook barbeingadapted to swing towards the tooth 106, bringing the hook in alignmentwith said tooth, when a can end is presen-t upon `the chuck 22, orremain `at rest, the hook being out of alignment with thej tooth,` whenthere is no can end upon the chuck 22.

.The hook bar 124` engages the tooth 106V during the downward motion oi`the arm 121,

`and pullingV down upon the rod 104, causes' the liftingo the needlevalve ott' its y seat, discharging lining` compound.

Foractuating the hook bar 124, a teeler rod 1261s made tof pass `throughthe `central opening 127' of the tubular stem 33, the lower endet said'rod extending downwardbeyond the chuck disc 32, while the upper endconnects with a beam lever 128, fulcrumed upon a lug 129, provided uponthe arm 30 and carryingV at the other end a rod 130, which passingthrough the inside of the tubular In the operation of the machine, a canend to be lined is placed upon the lower chuck 22 and the chuck israised, until it engages the upper chuck disc 32;` the lower projectingend ot the teeler rod 126 then comes in contact with the center of thecan end and is raised, rocking the beam lever 128, and lower` ing therod 130 and the arm 131;` of the belli crank lever; the other arm 133 ofthe bell crank, connecting Vby means of the link 134 with the `hook bar124, swings said hoo'kto# wards the sleeve 105, bringing it in alignmentwith the tooth 106, ready to pull upon it, when 4the arm 121 swingsdownward, and thus open the needlevalve.V y y In caseno can end hasbeenV placedupon the chuck 22, thefeeler rod`126 will not be raised bythe upward motion of the chuck, the projecting end of the eeler rodentering the hole 135, provided in the lower chuck, andthe hook barremaining out ofalignment with the tooth 106, as shown in Figure 6,will` `fail in its downward motion to pull the rod* "104 down and openthe needle valve.

Then it is desired to set the machine by' hand, so as to prevent theopening of the needle valve controlling the discharge of liningcompound, the tooth106 is turned toone side and out of alignment withthehook bar 124 by means of the handle 107. The downward motion of the hookbar will not affect then the sleeve 105 and the rod 104, andthe needlevalve will remain closed.

Forconverting the machine from an ar-V rangement lining can ends of oneshape, into an arrangement for lining can ends of another shape,thecanend magazine together with the can end feed slide andreleasinglba'rs, and the lower spindle 21 `together with the lower chuck22 and cam 24 are replacedby others conforming with the shape ofthe canendsto-belined."" f

In transmitting rotary `motion from the stationary mounted shaft 77 tothe movably mounted spindle 21, a number of intermediate gears wereusedas shown in Figure 4.

When the arm carrying the spindle 21 swings towards or from thestationary roller, said swinging affects the rate of rotation ot thespindle; the swinging of the arm against a clockwisedirection tendstoturn the gear' `81 againsta clockwise direction, turning theV gear23and the chuck 1n a` clockwise direc-S the lining compoundmorefevenly,the`posi! tionof the tubular shaft in relation tethelposition of the chuck, when its maJor axis is` in a direction across themachine, is so chosen, as to place the bifurcated arm in a direction atan angle with said or aXis of' the chuck, as shown in Figure 4.

The path of travel of the spindle 2l will be not along the center lineof the machine, but at an incline with it, the component part of themotion in the direction across the machine moves the can end flange inrelation to the stationary nozzle in the proper direction, and withsubstantially the proper amount to compensate for the disturbing effectof the swinging of the arm.
